A dilatation balloon catheter (10) includes a shaft (12) having a proximal outer tube section and a distal outer tube section. The proximal outer tube section (40) is formed from a tubular braid of a stainless steel member, which is encased in a polymer material such as polyimide. The pick count of the braid may be increased along the proximal outer tube section toward its distal end in order to increase flexibility. The distal outer tube section (42) is a tube made of a polymer material, such as a high density polyethylene.
Un cathéter à dilatation à ballonnet (10) comprend une tige (12) qui présente une section tubulaire extérieure proximale et une section tubulaire extérieure distale. La section tubulaire extérieure proximale (40) consiste en une tresse tubulaire constituée d'un élément en acier inoxydable qui est enrobée d'un matériau polymère, tel que le polyimide. Il est possible d'augmenter le nombre des fils de la tresse le long de la section tubulaire extérieure proximale en direction de son extrémité distale afin d'en accroître la souplesse. La section tubulaire extérieure distale (42) consiste en un tube réalisé dans un matériau polymère, tel qu'un polyéthylène de haute densité.
